Hi,
I'm interested in inspecting the chain plates on my 1978 CD-25. I'm not sure where or what to look for. Any suggestions?
Thank you

Inspecting Chain Plates on CD-25.

Re: Inspecting Chain Plates on CD-25.
I would check those suckers out and monitor them regularly.
I have a CD 28 and chain plates are underneath deck on/in bulkhead just under where mast shrouds connect on deck, on both sides of boat, inside. I don't know about the CD 25, but think they'd be in same general area, inside the boat.
Check them out - one of mine was rusted and scared me to death. I recentlyhad all bolts replaced/rebedded on shroud mounts going into top-deck and regularly oil and monitor my chain plates (look out for rust, stress fractures, etc). Shouldn't be much rust, corrosion or cracks in them (like on my original 20 year old plates). Otherwise, under sail stress, you could lose a mast, especially under SHOCK stress when or if your rigging JUMPS in high wind or on sail changes, jybes or tacks or otherwise.
If they are corroded, cracked, etc., seriously consider replacing them, a real chore. At least, check them and know what condition they're in -- better to know what's going on so you'll know if there's a problem, or potention problem. Better than getting stuck out on water and having to cut downed mast off boat with wire cutters, like me.
If in doubt, get a rigger, rigging specialist to look boat over - some surveyors can do it but I've had bad luck with them (they seem, these days with all the lawyers, to be too scared to give an opinion). Good yard repair guys, experienced sailors and riggers have really helped me learn alot, the hard way.
Good luck,

Re: Inspecting Chain Plates on CD-25.
Hi again! Thought I'd make other comments.
My problems were apparently caused by saltwater corrosion from water leaks from under toe rails and at bow chain locker. Trickle leaks from these areas over time, ran along top of liner where it connects to hull, hit the chain plates and ate them up. So, I also had my toe rails removed and rebedded with stout caulk. I also had my bowsprit rebedded and solved chainlocker leaks by sealing it off on outside while under sail, from rain, etc. There's still condensation down underneath deck where liner connects to hull, but definitely not like before. I watch this stuff closely now.
Electrolysis may also hurt you. A buddy of mine had an older Pearson that was not properly zinked. Overtime, electrolysis ate his chains plates up. A surveyor, on a marine insurance update survey, caught the problem before the guy got into trouble. I saw the plates - pretty thick ones - but I was shocked at how much electrolysis had eaten them up over time. Stress from too much sail or wind could have sheered one of the emaciated plates off - they looked like someone had poured acid on them - bizarre looking.
Just some more maintenance ideas.

Thanks for the reply to my question. I will definetly do some reading on the subject. My wife read your reply has agreed to try it one more time.. As to your question. I would suggest using the search feature of this page and search for "Chainplates" I do know one thing.
Cape Dory used Stainless steel plates as early as 1980. My 22 foot has them. Not sure before then, but I do remember a post that asked when the earliest SS chainplates were used.
Good luck to you , and thanks again!

Re: Inspecting Chain Plates on CD-25.
Recommend you look at the cross-section diagrams of chain plates in the owners manual. Thgey give a good idea how they are built. If you don't have yours, there's a 1981 Manual on line at this site under "Cape Dorys" section.
